Leech

Leech is a battle effect and a battle mechanic that appeared in Sonic Chronicles: The Dark Brotherhood.

Description
Leech is an additional effect to certain attacks in Sonic Chronicles: The Dark Brotherhood. It can be inflicted on both playable characters and enemies by using certain attacks, such as POW moves or regular attacks (enemies only).

When a target is hit by attacks that has the Leech effect, the user of the attacks regains Hit Points when they manage to damage a target with the said attacks. In gameplay, the sign that Leech attacks are used is when the target takes damage from the user's attack, which is shown by a orange number displaying the damage received, while the user of the attack at the same time regains some of its own Hit Points, which is shown by a green number displaying the Hit Points the user regains. If the user of the attack cannot regain any more Hit Points that they already have or misses the target, however, the Leech effect is nullified.
