Pokemon Fire Red Omega Regionlocke - Prelude to the Final Gym(also we finally beat Sabrina)

We finally defeat Sabrina(rather anticlimactically too might I add), and then defeat the last of the remaining trainers before the M Y S T E R I O U S final Gym Leader. Deaths: Sentinel(Sentret), WanShiTong(Hoothoot), Dende(Slugma), Burst(Elekid), Sharkigatr(Croconaw) Regionlocke Rules: 1. I can only catch the first Pokemon on each route that is from the region of my choice. I can also catch Pokemon that evolve into a Pokemon introduced in said region as long as no other Pokemon are available or I fail to catch the other Pokemon. 2. If a Pokemon faints, it is considered dead and must be boxed. 3. I'm gonna use items cause I suck at Nuzlockes(sorry, Hardcore Nuzlockers) 4. I must keep my Pokemon within the level cap of the next gym.(I am a bit flexible with this rule however since I am not using Rare Candies. A Pokemon one or two levels above the cap will still be safe.)
