Final Fantasy IX - Level 1 Freya defeats Meltigemini

ファイナルファンタジーIX - レベル1のフレイヤがメルティジェミニを倒す
Meltigemini is by far the hardest boss in the Level 1 Challenge, as all of his attacks are 1shot. Killing Meltigemini with a single character at Level 1 had always been considered impossible (like Deathguise) but here I am to make it possible (well, the RNG was also in my favor).
In this battle we cannot waste time because we could die at any moment, the most optimal is to kill him in 3 turns. At first I had thought of using Quina with Bad Breath but the chances of him/her hitting with it are only 4.7% (Meltigemini would be inflicted with Mini, Darkness & Slow). Quina just have 15 Magic Stones so we would activate him/her Auto-Reflect to avoid getting hit by Bio. Even if Bad Breath worked Meltigemini would still kill us with Viral Smoke, Venom Powder and Wings; Quina also would need 1 HP to use Limit Glove... too many turns and too much RNG.
Note: Meltigemini's Wings, once Bad Breath had taken effect, would deal 14 damage to Quina (47 Defense and Back Row) with 42% chances to hit.
At this point I only had 2 options left: use Zidane or Freya, since they both have a fixed damage attack (Thievery & Dragon's Crest). I opted for Freya because she is the party member that could have the most Evasion (41) at this time. Freya has 18 Magic Stones therefore we cannot cover ourselves from all of his attacks, so we have to choose and take risks. We have practically 3 combinations that we can make:
• Option 1.- Auto-Reflect (to avoid Bio)
• Option 2.- Distract + Antibody (to avoid Wings but not completely and Venom Powder)
• Option 3.- Auto-Life + Distract (to survive 1 time Viral Smoke or Bio, and to avoid Wings but not completely)
As you can see in all the options we have to take a lot of risk, we have to choose one and hope that the RNG is in our favor. IMO the 3rd option is the best.
