Olimar is a playable character in the Brawl mod Project M. He comes with his Pikmin in tow and a stronger moveset for Project M. Despite the power buffs, Melee physics and higher lag in most of his attacks have put him in an unfavorable position for Project M.
Olimar ranks 39th out of 41 on the official tier list, at the bottom of the D tier. This is an extreme drop from his tier placement in Brawl, where he was ranked 3rd out of 38, and is the largest any Project M character's standing has fallen when compared to their Melee or Brawl tier list.
In Brawl, Olimar excelled at defensive gameplay, being able to camp effectively with his Pikmin. These capabilities have put Olimar 3rd on the Brawl tier list. As Project M focuses more on offensive gameplay than defensive gameplay, Olimar's moveset has been consequently altered.
Olimar's Pikmin in Project M are stronger and have more endurance than before. Also, the Pikmin now have a mechanic where their strength is dependent on the type of flower on their heads. Besides the buffs to the Pikmin, Olimar's ground game has been improved, possessing more powerful tilts, smash attacks, and throws. Olimar's aerial game also saw some positive adjustments, featuring two potential KO moves in his up and down aerials. Finally, Olimar's recovery, Pikmin Chain, which was unreliable and low-reaching in Brawl, has been replaced with the more useful Ionium Jet.
However, Olimar has many weaknesses in Project M. While he is heavier than he was in Brawl, Olimar is still fairly light, making him susceptible to KOs earlier than other characters.
Changes from Brawl to PM
While Olimar received some buffs, he has been heavily nerfed overall in the transition from Brawl to PM. The most notable nerf Olimar received was the reduction to the amount of Pikmin he can have at one time which has been reduced to 4 Pikmin instead of 6. This greatly reduced Olimar's camping potential especially since the rest of the cast have better offence and the reintroduction of Melee mechanics have also sped up the rest of the cast which makes it easier for them to play around Olimar's defence. Besides this, Olimar's defence is also worse as his higher weight and fall speed when combined with the changes to PM's mechanics make him much easier to combo. As well as these changes, his smash attacks are laggier, Pikmin Throw with white Pikmin is notably weaker and now causes the white Pikmin to self destruct and Pikmin Order no longer has armor further hindering his defence.
Olimar has received some buffs however. Olimar's endurance is overall much higher due to him being heavier and his recovery is much better. His air speed is much faster and his new up special: Ionium Jet is a more reliable and consistent for recovering. His Pikmin's endurance is also much higher as their HP has been greatly increased and the flowers on their heads now determines their strength making them even stronger than before.
Overall, Olimar's greater endurance and offence does not make up for his less effective defence resulting in him being a much less effective character than in Brawl.
