so just wanted to make sure I am interpreting this rule corrrectly in the rules for companions:

• When a companion is put into play under a player’s control, if that companion was already in play under that player’s control, it is removed from the map first.

this is basically a companion respawn/reset correct? if the companion exists on the map elsewhere, you can respawn the companion removing the previous version as long as your spending whatever prerequisite of that heroes skill? like when Jarrod spends strain for Jax? I assume this effectively respawns/resets them with full health correct?

ah sorry, realized I posted this in the wrong sub forum...

Only one copy of each companion can be in play, so yes, if you create one, a previously existing copy gets removed. The new copy enters the game ready, without damage, conditions, power tokens, etc.

Jarrod can only use Droid Mastery if Jax is not in play. So it cannot be used as a quick teleport for Jax.

In the case of Junk Droid, a new droid comes to play, the old copy gets deleted.
