I made a post in combo thread about what I think is undoubtedly best stage for Lobo, Lagoon section of Batcave, so I'll just quote myself (expanded it a bit):
Lobo benefits greatly from exposed wires (also allows you to safely load trait) and makes them respect low starter even more which may open other possibilities.
Only thing to be mindful of and haven't seen really done by anyone yet is that they can attach the bomb on the elevator on the left side.
Do you guys have any other preferred stages?
P.S. Avoid Atlantis like a plague.
There are also not that many interactables that gadget characters could use on for resets and oki advantage, even if they blow up generator it's a half job done for Lobo.this is something I wanted to bring up, that lagoon part of Batcave might be one of better stages for Lobo because of b12 wires combo ability
you can do cool stuff like this and be really creative
b12, wires, j2, 113, MB toss, b3, f21, low hook 52% (55% w trait)
b12, wires, (load trait, wait a sec or dash under) b2u1, 113, MB toss, wires, dash, 12 1+3 59% (62% w trait)
b12 (or b2u1), wires, (load trait, wait a sec or dash under) b2u1, 113, MB toss, wires b2u1 spin cycle (to throw them in corner) 59%
4, 21, low shot, wires, (slight walk forward or dash under), b2u1, 113, MB toss, wires, b3, f21, low hook 50%
aa combo example
3, wires, b2u1, wires (depends on positioning) 113, MB toss, b3, dash 12 1+3 61% (63% w trait)
on the right side you can throw barrel (can be MB'd) and connect with MB space hook for 30% and throw them in corner
it gets better. since he rolls the barrel instead of throwing it, if they're close you can even do a quick dash and combo of it with 1 or 12 toss
barrel, dash 12, MB toss, 21, hook charge 41%
cj2, barrel, dash 113, MB toss, f21, hook charge 47% (49% w trait)
