Knowing that Castro was an avid scuba diver, the CIA developed an underwater mine which would detonate upon being picked up. The mine would be disguised in an ornate seashell, which would be planted in one of Castro's preferred dive sites.

The CIA developed a diving suit and breathing aparatus that was infected with fungus and tuberculosis. The suit would be delivered by an American lawyer conducting hostage negotiations in Cuba, who had no knowledge of the plan.

The CIA considered lacing Castro's radio studio with high doses of LSD so that he would totally embarrass himself during a national broadcast.

Another plan developed by the CIA that they believed could ruin Castro's reputation in Cuba was to slip thallium salt into his shoes. This would ultimately cause his hair to fall out (the primary target of this plan being his iconic beard)

The CIA developed a cigar that was packed with enough TNT to completely blow off Castro's upper body. The cigar would be slipped into his collection on his visit to NYC for a United Nations convention by a police officer.

The plan was never carried out, and when it was leaked, the public's reaction caused the CIA to report that it was merely a "joke," despite leaks by officials to the contrary.

The CIA enlisted the help of one of Castro's mistresses (the man had a sex addiction, sending his security out to pickup girls to bring back to his estate for sex after every meal).

Poison pills were to be smuggled into his bedroom and slipped into his food. The method of smuggling; a jar of facial cream. By the time his mistress arrived to his bedroom, the pills had dissolved into the cream. His mistress realized there was no way she could force feed him the cream and she became distraught.

Castro realized what was going on, took a gun from his desk and handed it to the mistress: pointing it at his head and telling her to pull the trigger. The mistress broke down and admitted to the plan but that she cared to much for him to do it.

"I flipped the chamber out and hit it back. He didn’t even flinch. And he said, ‘You can’t kill me. Nobody can kill me.’ And he kind of smiled and chewed on his cigar. … I felt deflated. He was so sure of me. He just grabbed me. We made love. I contemplated staying—to try talking to him later, after his speech, but it would be too late, because he rambles on for 8, 10, 12 hours. That was the hardest part. I wanted him to beg me to stay, but he got dressed and left. I just sat there by myself awhile. I left him a note. I told him that I would be back.”

what the fuck happened to the twink son of his "Justin"

Castro was to be listed at a couple of cents; to bruise his ego.

The plan called for using several submarines to launch hundreds of flares over the island, while having aircraft overhead blast "the voice of Jesus Christ" telling of his return. "Jesus" would then proclaim that Castro was the Antichrist and the only hope of salvation for the Cubans was to eliminate him.

Not much more. Seems like it was an idea floated by a military general

They offered to supply him with an ordinary looking ballpoint pen that contained a poisoned hypodermic needle that could be injected by pushing the button on the top. The contact thought this device was "useless" and requested high powered automatic weapons and ammunition. The CIA agreed and made the weapons drop.

They lost contact with the "government official" after the weapons were provided.
