Gear 5 can be considered the strongest gear that Luffy owns to date. The invincibility in Gear 5's state has broken all limits of "Straw Hat"'s power. So there are many fans who are curious about Gear 5's weaknesses , because with "dirty buffs" like that, this series will be much less attractive.
What is Gear 5?
There is no doubt that Gear 5 is not only one of the most powerful devil fruits in the One Piece series, but is also considered an "unparalleled" power. When Luffy uses the Sun God Nika form, his abilities are limited only by his own creativity and imagination. This makes many fans think that Oda is "dirty buffing", making Luffy an invincible existence in One Piece.
However, Gear 5's weakness can directly affect Luffy's combat performance. If his opponent discovers this, Luffy may face many challenges and difficulties in using this power.

Gear 5 shortens Luffy's lifespan
After Luffy's meridians were "broken" by Kaido, Gear 5 seized that opportunity and immediately took over his body. Immediately after that, Luffy burst out with unbelievable power, which made Kaido extremely excited. However, Luffy often loses control during his transformation.
Not long after using Gear 5, Luffy's face began to sag because he had "reached his limit". This is the Gear 5's most obvious weakness . In case he becomes dependent on Gear 5, the "Straw Hat"'s lifespan may be shortened.
Furthermore, Luffy previously agreed to give up part of his lifespan after the surgery with Ivankov. Therefore, Luffy really needs to carefully calculate every time he uses Gear 5 to ensure this huge source of power does not cause him to "slowly die".

Affects other Gears
In addition to Gear 5, Luffy also owns many different Gears. During the battle with Lucci (CP-9), Luffy displayed Gear 2 which increased his speed and strength, but this Gear made him "paralyzed" immediately afterwards. After that, Luffy created Gear 3, which allowed his body to expand at will to crush large objects.
During the timeskip, Luffy created Gear 4 while training with Rayleigh. This gear has three different variations: Bounce Man, Tankman and Snakeman. While Bounce man significantly increases damage, Tankman focuses on defense, and Snakeman helps increase Luffy's speed.
All of Luffy's Gears amplify the Straw Hat's power in different ways, of course he can only use them for a limited period of time. Furthermore, because Luffy is not yet proficient in using Gear 5, his overall stamina continuously decreases, thereby affecting the usage time of other Gears.
Above are the weaknesses of Gear 5 that Luffy is suffering from. Do you think Luffy can fully control this power and soon achieve his dream of Pirate King?
