Contending duplicate hubs for "Les maîtres du temps" aka "The Masters of Time"

Question

A relatively popular story ID subject (with six confirmed answers and several additional probable answers) has something of a mess with respect to duplicate management.

The first time that this was asked about was in Feb 2013, and it was answered and accepted then:

1. 80's Animated movie: An old man joins mission to save a boy stranded on a hostile world

Some duplicates were later closed against it:

• trying to identify SF anime film shown on British TV in 1980s or '90s
• Please help to identify an animated movie: a boy lost on a jungle planet (80-90-s)

Some years later in May 2018, this movie was asked about and got an accepted answer for a fourth time:

2. Animation movie (80's-90's) with brain-sucking insects

At that time, #1 was closed as a duplicate of #2, despite the fact that #1 was already a duplicate hub. This created a duplicate chain.

Some later duplicates have also been closed against #2:

• Space-themed cartoon film seen on TV in the mid-80's with a pair of blobby telepathic aliens and relativistic aging
• Animation (possibly anime) with space station made of two hemispheres

In addition to a new question today that will be a duplicate if its answer is accepted (1980s sci-fi anime film with a scene where a human boy and an alien are walking through a swamp, and the alien is caught and killed by living vines), there is also an old question with an accepted answer that should be closed:

• Fantasy Animation from the 80's. Companion pulled into ceiling by tentacles. Other turns around and companion is just 'gone'

What's the best way to resolve this tangle and establish a proper hub question for current and future duplicates?

Answer 1

I pointed all the confirmed duplicates (new and old) to question 2: Animation movie (80's-90's) with brain-sucking insects

(I think this was the first time I had changed dupe targets without actually reopening any questions.)
