SPOILER WARNING: This article contains major spoilers for "Mixed Signals," the latest episode of The Flash.
In "Mixed Signals," the latest episode of The Flash, Barry gave his new suit a whirl -- but it didn't go exactly as planned. During Barry's time in the Speed Force, Cisco went to town on the Flash suit in the hopes that Barry would eventually return. By the time Barry was able to wear it again, Cisco had packed it full of technology, which became more of a hindrance than a help when the Scarlet Speedster went up against the technopath Kilg%re.
Before Barry went toe-to-toe with Kilg%re, Cisco explained that the new suit had a lot more features than the old one did. As if to prove that point, he handed Barry a massive user's manual. Barry quickly dismissed the user's manual, putting it aside and taking the suit for a spin as soon as someone was in trouble.
However, as soon as Barry came in contact with Kilg%re himself, he was in trouble. Because of his technopathy, Kilg%re was able to take remote control of the suit, effectively locking Cisco and Team Flash out. The first thing Kilg%re used was the Pulse Cannon, which shot a bolt of Speed Force lightning out of the palm of Barry's glove and incapacitated Kid Flash. The use of the Pulse Cannon also revealed that the suit has a full weapon system, including targeting.
Barry was able to flee before Kilg%re used the suit's defibrillator to kill him. However, Kilg%re's control caused the suit to glitch. Iris urged him to take off the suit, but the deadlock function was enacted; Cisco had installed that feature so that a villain could not unmask Barry if he was ever knocked out, but it effectively trapped him inside the suit. The malfunction also employed the flotation feature, as seen in the trailer for the episode. Finally, the suit enacted the Babel Protocol, a self-destruct sequence which was intended to destroy evil Barry doppelgangers like Savitar.
As Cisco struggled to regain remote access, his control panel revealed several other features that were not shown in action, including fire suspension, temperature control, comms, navigation and R-SK8S, which may indicate the suit has roller skates. The suit also has an AI with Cisco's voice.
Considering the trouble all this technology caused, Barry seemed eager to table the suit and go back to basics at the end of the episode. It is unclear if he will use any of these functions again.
Starring Grant Gustin as the Scarlet Speedster, The Flash airs Tuesdays at 8 p.m. ET/PT on The CW. The series also stars Jesse L. Martin, Tom Cavanagh, Carlos Valdes, Candice Patton, Danielle Panabaker, Keiynan Lonsdale and more.
