Are there any minicons that turn into weapons that were available separately from a larger figure? I know some Cybertron guys had target master style partners, but I'm looking for guys I can use as weapons for my PCCs without breaking up a pairing - I don't like using accessories from one TF for a different one I know about the Armada sword planes, and may look into getting one of those, but if there's any others, I'm all ears
The Armada Emergency Mini-Con Team are all weapons-bots as well, as are the Air Military team. There are various redecos of them to help give you other options and possibly easier finding.
I tried to find them in the resources section, but they're split into the individual bots rather than the teams. Check them out here though; Firebot - Transformers Armada - Transformers Resources Gunbarrel - Transformers Armada - Transformers Resources Makeshift - Transformers Armada - Transformers Resources Prowl - Transformers Armada - Transformers Resources Terradive - Transformers Armada - Transformers Resources Thunderwing - Transformers Armada - Transformers Resources
Road Assault Team can form a shield called Sky Boom. http://www.tfu.info/2003/Mini-Con/Mirage/skyboom.jpg
The grand majority of the minicon trios from Armada used one of several gimmicks: combined form firing missiles third, weapon mode action feature when rolled or connected to Cyclonus
