Suggested by Sonic Lugia is a Pokemon of legend with immense psychic and wind abilities but those won’t be enough against a DBZ fighter like this. Gero is fast enough to dodge all of Lugia’s attacks while being strong enough to utterly crush him with power. Lugia likely wouldn’t last more than 1-2 shots before going down because that’s how great the difference in power is between the two of them. No matter how you slice it, Gero has the edge here. Dr Gero wins.
