I am finally finished my transformable transformer but i still have one problem.... i cant think of an awesome name for him. So, i'm open to suggestions. Anyway, i added his arms and followed Dark Watch's idea and made the front end split in two(thanks Dark Watch!). I also changed his chest so it would open up and allow a chest plate to rise out. Oh, and i added a ton of little parts here and there so he wouldn't look as blocky. I still want to add some color to him so this is technically still a work in progress. Hopefully i will have the finished product posted no later than next weekend.
Nice job, man! I'm glad I could help you out with your dilemma. As for a name... I used to play a game called Tibia, and on Tibia there were these monsters with really long arms and legs called Shadow Stalkers (I think; it's been a while sence I've played), so why not call him Shadow Stalker or something of the sort?
By the way would you mind looking at my transformer? http://www.mocpages.com/moc.php/161763
