Splodyhead is an experiment controlled by his fiery disposition: he is fierce, greatly dislikes the water, and is shown to be hotheaded when provoked. He is loyal to his friends, but he does have an attitude. He knows when he's outnumbered, so he will often pick off his victims one by one. He likes his food "well done", as Lilo puts it, which usually means he burns or melts it. While he cannot talk (though he does understand what people are saying), he can still be intelligent and polite, as shown in "Slushy" when he thanked Jumba for fixing his thermostat so he wouldn't overheat. He is known to be hostile and apparently shares a grudge with Slushy due to his opposing elemental power, but they resolved it in "Spike".
Splodyhead is a small, red six-legged (two arms and four hind tentacles) dragon-like experiment. His head has a hole-like nose and fangs sticking out from his mouth, two red antennae, a red and purple striped horn on his head with brick-red markings on his forehead and back, dark blue eyes with purple-red spots around them, and two short red ears. He has red fur with a sort of pink fur on his underbelly extending to his mouth, and a short tail. Splodyhead is shown to have a turquoise tongue.
Powers and abilities
Splodyhead can fire plasma blasts from his hole-like nose. In "Slushy", this power is expanded upon, showing that he can channel these plasma blasts in streams of fire and/or shoot flames, which he can manipulate into types of shields. He can also substitute almost any solid sphere (such as softballs) for his plasma balls if inserted into his nozzle/nose, and blast it with just as much force. Splodyhead can propel himself by shooting out his plasma streams similar to a rocket.
The Stitch! anime also revealed that Splodyhead can lob spheres made out of a horrible stench after being modified by Hämsterviel.
In addition to his plasma-based abilities, Splodyhead is able to climb and maneuver around steep walls and cliffs.
Experiment 619 was the 619th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to use his fiery plasma blasts to cause massive chaos and damage. 619 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.
All of the experiment pods were released and scattered across the island of Kauai.
619's pod was eventually discovered by Lilo, Stitch, and Gantu, who were all seen competing for the pod as they chased after it while causing an outdoor ruckus, unintentionally disrupting a wedding ceremony at one point.
During their struggle, a seagull snatched the pod and took it back to its nest on a cliff face near the Forbidden Island of Niʻihau. When the gull was unable to peck 619's pod open, it kicked it out of the nest in anger. The pod landed in the ocean, activating 619, who quickly jumped ashore and then proceeded to take over the seagull's nest.
Later, 619 spotted Lilo, Stitch, Jumba, Pleakley, Experiment 625, and Gantu arriving on the island for him. Becoming extremely hostile, he attacked and destroyed both factions' campsites, which put the six in jeopardy. Stitch and Gantu, believing the other one was at fault, had a short-lived battle with each other before Lilo intervened to break it up.
When the two factions saw 619, whom Lilo named Splodyhead, invading the nest, he attacked with raining plasma blasts, forcing Lilo, Stitch, Jumba, Pleakley, Reuben, and Gantu to take cover. Using his plasma attacks, Splodyhead managed to keep the six trapped, yet refused to come down to finish them off, due to him being outnumbered.
While Splodyhead waited to pick them off one by one, Stitch and Gantu resumed their conflict, since they both thought the other one was evil. Realizing what Splodyhead was up to, Lilo told the two rivals that if they wanted to be rescued, they would have to put their differences aside and try to work together. Stitch and Gantu initially refused, but after both factions took a vote, Lilo was nominated to lead them.
As more time elapsed, the six built and sent out a decoy raft as bait, which Splodyhead targeted and blew up. Convinced the danger was over, Splodyhead left the nest, thus allowing Lilo and Jumba to ambush him and temporarily incapacitate his weapons with water. Defenseless, Splodyhead attempted to escape back to the nest, but was stopped when Stitch tackled him, enabling Gantu to capture Splodyhead in a makeshift net and put him into a containment orb.
Realizing they had worked together, Stitch attempted to make amends with Gantu by shaking hands with the latter, but Gantu ungratefully pushed the former aside. The two factions and Splodyhead were soon rescued from the island by Nani and David driving motorboats, but not before Lilo briefly lectured Gantu's brash nature.
Splodyhead was shortly after taken back to Kauai, where Lilo and Stitch found him a one true place lighting tiki torches at the luau. He also charred a piece of cake with his fiery plasma before devouring it.
In "Houdini", Splodyhead was one of the audience members for Stitch's bungled magic act.
In "Slushy", Jumba adjusted Splodyhead's thermostat so he wouldn't overheat in hot temperatures, to which he politely thanked Jumba in return. Splodyhead was later sent to Slushy's ice palace to defeat the latter. After a long-drawn-out battle between the two experiments, Splodyhead was defeated when Slushy froze him into a block of ice. He was later freed and blasted a fireball into the sky at the top of Waialeale Peak to clear Slushy's snowstorms.
Splodyhead reappeared in "Slugger" as part of Lilo's softball team.
In "Spike", Splodyhead was one of the experiments in Pleakley's E.A.R.W.A.X. group. When a stray snowball from Slushy accidentally hit Splodyhead (who had suffered from boredom), a battle ensued between the two experiments, which ended when Pleakley convinced Slushy and Splodyhead to attempt hugging therapy on each other.
Later, the first 624 experiments, including Splodyhead, were rounded up by Leroy and taken to a stadium to be destroyed. However, Lilo, Stitch, Jumba, Pleakley, Reuben and Gantu arrived before the experiments could be destroyed.
Splodyhead participated in the following battle between the experiments and the Leroy clones by blasting Leroys away with plasma attacks.
However, the Leroys soon gained the upper hand in the battle but were defeated when Lilo, Stitch, Reuben and several other experiments performed the song "Aloha ʻOe", which caused the Leroy army to shut down due to the original Leroy's fail-safe.
Splodyhead made a cameo appearance in the Stitch! anime as one of the experiments in Hämsterviel's prison cell. He has also made a number of other appearances, twice with Plasmoid. In the first appearance, Splodyhead and Plasmoid combated Stitch when he was hypnotized by Swirly into fighting for Hämsterviel. In the second appearance, Splodyhead and Plasmoid were modified by Hämsterviel to attack Stitch. Splodyhead was given a new ability to fire purple balls of a repulsive odor. Also, after the effects were reversed, Splodyhead could expel pink gas of an aromatic smell, the opposite of his modified ability. In "Shogun", it is shown that Splodyhead was dehydrated back into an experiment pod and locked in Jumba's vault. He made a final appearance in aiding Stitch in battle against Dark End.
- In his debut, Splodyhead's number was pronounced as "six-nineteen" by Jumba, rather than the typical by-digit pronunciation of most other experiments (which would be "six-one-nine" in Splodyhead's case).
- Splodyhead is one of the rare experiments to not have black eyes like most experiments, having dark blue eyes instead.
- Splodyhead, along with Nosox, Richter, Butter, Tank, Gigi, Shortstuff, Yang, Spike, Phoon, and one unconfirmed experiment, are the only known experiments that are primarily quadrupeds.
- Splodyhead's pod color is blue in the original series. In the Stitch! anime, it is red.
- In "Slushy", Jumba somehow erroneously referred to Splodyhead as 515, a number taken by Deforestator.
- Splodyhead appears to share a grudge with Slushy, but they resolved it in "Spike".
- Splodyhead's head appears in the online game Jumba's Lab.
- Splodyhead made a cameo in Big Hero 6 as one of the pillows on Fred's bed. This makes him the only experiment other than Stitch to appear in a Disney Animated Canon film.
