Motux, I wonder (if you have time) if you know what batteries Ultron takes? I've been trying to find out for him and for Iron Legion (don't know if you have that one too or not). Reason is I'm trying to get a soap reactor so I can have them lit in a display without the need for batteries - Ultron just looks so much better lit judging from the photos.
My guess is Legion takes 12 of the LR621 (3 in each arm, torso and head) and the same for Ultron (since that's what I've been noticing for the last few Iron Man figures I've gotten) - but since Ultron is bigger and it looks like his upper and lower arms light up I was wondering if he uses more batteries, or 12 of the LR41 (used in IGOR), some combination, or different batteries altogether?
I've always seen batteries used in sets of 3 for all the figures I have, except for the Star-Lord lit helmet which only had 2 batteries instead of the usual 3.
Any help on this is much appreciated - thank you my friend!
