Very close, though

Mars is the Guardian of Passion (she is so fierce!) but Sailor Jupiter is the Guardian of Strength. I believe she is a bit more powerful than Mars.

hahaha... this is funny. i used to be so into fortune reading, zodiac, and birthday reading, face reading whatever, and yes i am also an aries, but ironically, i dislike her back in the early 90's along with many people, although tolerable in the manga/crystal, but i still don't give any damn or importance, she is so overrated anyway, and favorited by the animators especially in the old 90's anime, which i don't care, as i hate overrated, more than the main protagonist, i just want more Jupiter. so anyway, i turned my back all on those now... but as far as this topic goes... first of... aries, saggitarius are a fire sign... if you must know. although sags, are more cooler and fun to hang out, and not easily angered... but when they do... watch out... get my drift?! passion?! well i am passionate about my love for this and that... etc. but it does not freaking mean that other people or other zodiac can't become passionate about something, like for example, cooking. mars passion is her fire. as in literal fire. and jupiter is passionate about nature, and cooking, dont misunderstood. lol. when it comes to as a lover... everyone can be as passionate as any zodiac. duh! especially if they really love one another. there is no such thing as zodiac. its all in your head. sorry, hahha... i just preached that i am an aries, but i am also bias, cause i totally don't want anything to do with those anymore. well, hard habit to break. but getting there. and yes... i won't be bias... their powers are close, but Jupiter in my opinion is a bit higher, due to her strength, without having to transform, but in the crystal, i felt that biasness again was hanging in the air, for dear jupiter. especially the latest one. have you seen? episode 17? or something, with mercury abduction crystal?. i was so pissd off... after seeing it. so bs bias. they should also remember that Jupiter has old fans, and new fans, in different generation.

GOOOOOOOOOOOOOOOOO LITA, I LOVE YOU!!!
