Splodyhead, A.K.A. Experiment 619 and Splody, is an illegal genetic experiment created by Jumba Jookiba. He is designed to attack using fiery plasma blasts from his nozzle-like nose. His one true place is lighting tiki torches at the luau. He is voiced by Frank Welker.
He was activated when a seagull kicked his pod out of its nest and it landed in the ocean. He is shown to not like being in the water. He apparently comes over to Lilo's house, as shown in "Slushy". He helped to fight Slushy (523) with fire against ice. He was also one of the players on Lilo's softball team in "Slugger".
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 him 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 reptilian doglike experiment with a hole-like nose. He has a red and purple striped horn on his head with brick-red markings on his forehead and back. He has dark blue eyes with purple-red spots around them, two short red ears, and sort of pink fur from the bottom end of his belly all the way to the bottom of his mouth. He also has a turquoise tongue and a short red tail.
Splodyhead is a cunning and relentless predator. He can fire plasma blasts from his hole-like nose, and this is achieved by a small nuclear reactor inside his body. He has also shown to channel these plasma blasts in streams of fire and/or shoot flames, and has displayed the ability to manipulate these flames into types of shields – one shaped like liquid flames/lava, and the other shaped more like flames – and even once created a large monster-like shape out of it, making it stop towards his victim. He has the ability to fire purple balls of a repulsive odor while under the effects of Hämsterviel, and has also shown to release pink gas of an aromatic smell. He can substitute almost any solid sphere for his plasma balls if placed or thrown into his nozzle/nose, and blast it with just as much force.
Splodyhead can also see in the dark, has heat vision, a targeting scanner, and zoom in/out abilities. Splodyhead's feet and hands create a sticky substance which lets him scale walls and ceilings, similar to Stitch. Splodyhead is able to stand either on all six of his legs, or on just four.
Water is shown to temporarily incapacitate Splodyhead's plasma-shooting ability. Also, he cannot swim and is unable to use his cannon when hurt badly.
Splodyhead has appeared three times in the Stitch! anime, twice with Plasmoid. In the first appearance, he and Plasmoid fought against Stitch when he was hypnotized by Swirly into fighting for Hämsterviel. In the second appearance, he and Plasmoid were modified by Hämsterviel to attack Stitch. Splodyhead was given a modified ability to fire purple balls of a repulsive odor. Also, after the effects of Hämsterviel were reversed, Splodyhead was able to expel a pleasant aroma, the opposite of his modified ability. He made a third appearance in aiding Stitch in battle against Dark End.
- Splodyhead's pod color is blue.
- Splodyhead is described by the experiment computer screen as, "Experiment 619. Primary function: Plasma fire shooter".
- In "Slushy", Jumba erroneously refers to Splodyhead as 515, a number taken by Deforestator.
- 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.
