Acid used to be a venom symbiote that got transported to the ultimate weapon in Skylanders trap team, and fell on some traptanium, then was transported to Okarra and went into the orange lantern central power battery, then was transported to the triangulum world and found a secret room with a dead triangulum that hadn't faded away, so he went into the dead triangulum's body and claimed it as its own. Also, he can only see by heat, and energy
As you know, the contest is over and the winner is DragonMagic_Awesome. The dead triangulum was Rexevous and he was a powerful tri in a great war, but then his nemesis kept into his house, and killed him, then put a spell on him so he wouldn't fade, then kept his body like a trophy. Eventually, the Nemesis died, and Rexevous' body was lost, until now. Copyright of Marvel, DC, and Skylanders trap team.
