When a figure is promoted, to tokens transfer to the new figure, and also, can the new figure act right away (even if the figure they replaced was already given an action that turn)?

To elaborate further on the issue. The exact event that occured was Weapon X killed an opponent, and luckily promoted up to Wolverine. Now he's in position to charge another. Battlefield promotion doesn't have any rules on action tokens, as far as we've found.

The closest things we can relate it to is Alter-ego and Split-Merge Rules for token placement on exchanged dials. However, this isn't referred to as either of these. Thanks for the assistance!

Page 6 of the rules:

REPLACING CHARACTERS
Certain game effects will call for a character to be
replaced with one or more other characters on the
map. When assembling your force, you identify
these replacement characters although they are
not yet on your force. Replacement characters’
point values are not added to your build total. All
players should agree on the maximum number of
replacement characters allowed per force.
While replacement characters are off the map,
they should be positioned on their KO click. When a
game effect causes a character to be replaced:
• Tokens assigned to the replaced character
are assigned to the replacement character,
including tokens for the action that placed
them on the map, unless otherwise specified
by that effect.
• The replacement character must occupy
squares that were occupied by the replaced
character. If this is not possible, the
replacement character may occupy squares
adjacent to squares that were occupied by
the replaced character.
• If the replaced character was given a nonfree
action this turn, then the replacement
character is considered to have been given a
non-free action this turn as well.

Right on, Cheers mate! Thank you for the clarification!
