This is a short TAS of Ninja Storm to demo what the Green Samurai Ranger can do for a speedrun, using his flame sword and Super Samurai mode to blast through the first level at record pace.
All rangers in the game uses a sword of some kind as their main weapon, but can also switch to their alternate weapon by picking them up as a power-up from crates. Additionally, collecting a weapon of the same kind will upgrade it up to level 3. In the Samurai Ranger's case, this is the flame sword, which he whips out in front of himself to deal damage from a somewhat longer range than his sword (though never able to reach the end of the screen like the other rangers'). This is normally a clunky weapon to use, since the attack lingers a small bit, and the ranger has to keep his feet firmly planted in the ground while it's in effect; However, the attack can be used much quicker by using it in the air, as landing will cancel it out. Also worth mentioning is that the flame sword can potentially hit enemies multiple times during its duration; This attribute goes unused in the TAS though.
Super Samurai mode is the Samurai Ranger's ability, which can be toggled by pressing the select button. This will slowly drain the ranger's HP to the point where a single hit will cost a life. But this drain is ultimately not fatal, and by the power of TAS, no hits will be taken anyways. The effect of this mode are very beneficial to a speed run, as not only will it cap the ranger's weapon level to its max (allowing the flame sword to reach its max range), but it will also double his power output, allowing him to one-shot red enemies, which normally take two hits in normal mode.
Finally, of course, TAS makes the western duel-esque Megazord fights completely trivial, allowing for frame 1 inputs of the necessary combinations of button and direction.
