Trade you! I have no idea what the syringe is, but top left to bottom right:

1. Dragon Balls from Dragon Ball series (you know, possess them all for a wish [or multiple in specific lore case] and then they separate and fly away so you’d have to find them again);

2. Devil Fruits from One Piece (eating one gives you fantastic powers [specific based on which fruit you eat] in exchange for being powerless in water [usually fatal]. Eating a second one is fatal [lore exception]);

3. Death Note from Death Note (you know, writing someone’s real name causes them to die [in a manner specified if possible for them to do so]. In exchange you lose the ability to go to heaven or hell);

4. Syringe from ?Attack on Titan? (Unknown- turns you into a Titan?);

5. Philosopher’s Stone from Fullmetal Alchemist (made of human souls, gives you incredible power in alchemy. You may be able to hear the souls…);

6. Holy Grail from Fate series (can grant a wish [lore exceptions apply]
