Hey man dont listen to anyone telling you that Lex is a bad zoner. He has some really annoying setups that are almost impossible to get past if you dont know them beforehand. If you see a Lex player throw out a probe you MUST respect it. If they throw one out full screen, there is a good chance that they will follow up with the unblockable laser. After he points at the ground for the laser, you need to be moving or it will hit you. Generally you need to jump the probe shot while moving forward, but both of your characters also have other options. With flash, immediately use RMS when you see a Lex player point to call down a laser and this will help you get in and punish. This also applies to green lanturns "hold onto jet move" haha. Green lanturn can completely hold down lex and prevent him from using any special moves if you use his primary projectile at full speed. Most zoning beats Lex's zoning because his moves have very slow startup, so just try to keep him locked down.This will often make lex players jump in on you, which GL can AA for full combo damage. Lex is a momentum character in all aspects of his gameplay so dont let him get that momentum from full screen. The most dangerous projectile is his mine because he can combo off of them for an easy 40%. Flash's move out of RMS go right over these, but still be wary of any mines on screen. His fireball is nothing to really worry about. Even if it is hitting you, it does the same damage As deathstrokes low gun chip haha. NEVER be afraid to traid fireballs with a Lex. That is a winning battle for you.
