Mega-Glue is a super-strong adhesive created by Doctor Robotnik. Liquid at first, the compound is designed to harden in second, bad news for whoever might get themselves stuck to it. Stephen Squealbird, Robotnik's alter-ego, used it on Sonic the Hedgehog, Amy Rose and Johnny Lightfoot, condemning them to be stuck together forever. His plan backfired when Sonic stretched the glue around Robotnik, trapping him too. A Trooper sprayed Robotnik with an antidote, but the Freedom Fighters were also freed. Mega-Glue was never used again.
