Octobulb

Octobulb is a miniboss from Mega Man 10. It is a large lightbulb with eight wires coming from it, suggesting an octopus-like appearance. It appears in Sheep Man's stage, as well as the second Wily stage. Octobulb is only vulnerable when it is illuminated, which occurs by charging electricity via running on a treadmill in its lair. When its electricity runs out, it produces electric shocks which run back and forth along its wires. Octobulb can also create two small lightbulb-type enemies which follow the player.
