The team of Rex209 and Blue were first introduced in Test Subject Complete, when Rex209 was built. Before then Blue simply operated in a protosuit. This protosuit gained a melee attack in Test Subject Arena that utilized a proton sword which is used as a side special in their moveset. Rex209 has the unique ability to walk on ceilings, which is reflected in this game through their wall cling ability. Rex209 also has a proton blast which can be rapid-fired at enemy enzymes. In Test Subject Arena 2, Rex209 gained a melee attack that involved a stomp on the ground, which is transferred as a down special in the moveset. It is in this game they also acquired some of their taunts such as the victory dance, which would be performed whenever Rex209 won a battle in the arena.

Blue and Rex209, the test-taking team of Test Subject Complete. The intelligent Blue enzyme's strategic superiority combined with the mechsuit's powerful weapons and technology make them the perfect fit for a battle. Let's jump right in and look at their special moves.

Their neutral special is the most iconic attack of the testing duo: the Proton Blast. This move has good range and deals decent damage, especially when charged up completely. Their side special is Proton Sword Slide. A blade of proton energy is emitted from the tip of Rex's cannon and is then thrust forward as Rex charges. It has a rather short range but can deal quite a bit of knockback. The up special is Proton Laser, in which Rex fires a beam of proton energy straight downwards. The recoil from this powerful laser blast boosts them high into the air. It is great for vertical recovery, but has poor potential for horizontal recovery. The laser blast will damage any opponents below that are unfortunate enough to be hit by it, and any opponents that come into contact with Blue and Rex will also take damage.

The down special for these two testers is Stomp. This move involves Rex stomping the ground with great force. Any opponents directly hit with it will be burrowed into the ground, setting them up for a combo. The stomp also creates a miniature quake that will toss nearby opponents into the air, also perfect for getting a good combo out of. Their super attack is Mechsuit Rampage. It is much like Professor's in that Rex grows in size and power. However, Professor's super attack does not last long, but has a lot of strength and power. Blue and Rex's last a bit longer, but does not have the same amount of power behind the proton blasts. I suppose that's because Professor upgraded his a bit more...

The standard attacks for these guys have been enhanced.

Blue and Rex have loads of attack power and strength, but they are lacking in speed and jump height. They make up for their low jump height in their great vertical recovery, but the weight of the mechsuit still drags them down. They also have poor throw attacks, with short range and low combo opportunity.

Blue in Rex209 is still a powerhouse nonetheless. They have extremely strong attacks and deal lots of knockback, and many of their moves set up potential combos very well. In conclusion, these two make a great team and are very well-rounded in the SSN2 arena.
