This is not a bad Transformers series but it's not a great series either, but it's overall plot is that as the war between the Autobots and Decepticons a third faction of human-sized Transformers called Mini-Cons that could link with the Autobots and The Decepticons and grant them more power and with 3 teams that could combine into a sword, shield, and rifle can tip the balance to one side or the other, The only problem is that the Mini-Cons make the bigger Transformers too powerful and Optimus Prime sends the Mini-Cons away from Cybertron but the Decepticons attack their ship and half of the ship crashes on the Moon and the other half in mountain on Earth. Millions of years later three kids Rad, Carlos, and Alexis discover the ship and reactivate the Mini-Cons and this sends a message to Cybertron so the Autobots and Decepticons arrive to collect as many of the Mini-Cons as they can, but the more Mini-Cons they find and use awaken a greater evil: Unicorn!
This more like "The Transformers" meets "Pokemon" the animation is not the best and there are a lot of mistakes with characters being called the wrong names. Alexis is OK, but Rad and Carlos are annoying as are the 2 stupid bullies (a Bulk and Skull rip-off from "Power Rangers") and the five at toward the end wear space-suits that homages to outfits wore by the heroes of the anime classic "Battle For The Planets".
Armada is no classic by any means but it's fun and it;s take on Starscream and his constant back-stabbing and betrayal of Megatron is different and refreshing. It's worth a look.
